Be it known that we, CHARLES A.KEITH, ot' Danvers, Essex county, JEREMIAHKEITH, of Charlton,A

lVorce'ster county, and THOMAS KEITH, of Lynn, Essex county, all in the State ofl Massachusetts, have' invented an Improvement in Folding and Ironing Shoe-upper Edges; and we do hereby declare that the following, taken in vconnection with the drawing which accompanies and forms part of this specification, is a description of our invention sniiicient to cnable those skilled in the art to practice it.A

The invention relates particularlyto an organization of mechanism for turning or folding' tlie edgesof boot and shoe uppers, and pressing said folded edges prior .to the stitching thereof', or vthe application of binding thereto. l

'lhe invention consists primarily in combining'a work-supporting surface, a doubling or folding-guide, and a vertically and horizontajl y.reoiprocatin g presseriron, which, being heated, presses down and irons the turned-over lf dges-to facilitatethe stitching thereof'. v

The drawing represelits -a machine embodying the invention.

A shows a side elevation. l, a rea-r end elevation.

l, a front elevation.

' '1), a plan of the machine. v

t a denotes a bed-plate, at the front end of which is a post, b, supporting upon its top a horizontal table or work-supporting surface, c.

d is another post, rising from the bed Z1, and hav-- ing a long horizontal arni, e, extending length wise over the bed, as seen at A.

, Pivoted upon the top of this arm is a lever, f, having xed upon its front enda heater and presseriron, g. ,l

` The leveris'pivoted, or rests and moves vertically upon the rean'end ot' th arm e, as afulcrnm, and

a vertical pin, 7i, extends from the arm through the lever, the lever swinging horizontally upon this pin.

The front arm of the lever is normally held down towardthe arm elby-a spring, y,and, when thus held, the bottom and smooth surface of. the iron g` fpresses down upon thetop 'of' a vertical swing-bar or post, k,

pivoted by a pin, l, to the post b, and heldin normal position by a spring, fm, the piece k projectingthrongh an opening made through the table c, this opening being made of such length as to permit the swingpiece to move laterally with the \vork, and the top surface of the swing-piece being-flush orapproximatc-- ly ilnsh with the top of the table c.

The rear'arm n ofthe lever d is bent, and extends under a driving-shaft, o, to the peripheral surface of a cam, p, upon which it is held by the spring i.'

A cam projection, q, upon the cam-wheel, presses andthe iron g.

As the cam project-ion passes the lcverfarm, the4 spring throws down the iron upon the work, and,v

when in contact with the work, the iron is moved for-l tis a stationary plate, fastenedat its rear to vthetop of the table, as seen at a, and'tlien rising above the table, as seen at e, and having its front end bent under, and formed into a long blade, w.

x is a curved doubling-guide,,having one edge extending under the blade w, and its other edge over the said blade, as seen atA aud D, this guide being fixed to the front end of a yielding "piece, @turning on a' pin, z,- and held 1np toward the blade 'wbya spring.j, a suitable-lst-,op determining the extent ot' theforward movement of thevfolder, so as always to leave an open space-between the blade and the folder, to'allow the work to pass freely through'. l y

The doubling guide or folderureceives thc edgeof the work ilat'wise, but as the edge isfed through thefolder, the upper lip graduallyturns the edge over thebladc w, so that,. as ,the work, with its vedge turned over, passes underthe iron,.it is vin position to bc pressed and smoothed downby the. ironing mechanism.

The -iron may be heated by a gas-burner at the :end of a gas-pipe, the jet being directed into the iron (made hollow) or against its surface or suitable heaters. maybe placed in or removablyattached to the iron. j

To allow the foldinlglgnide to yield to irregularities im the thickness of the material, or to unevenness in the-edge thereof', it is provided with vthe spring j,'which, while keeping it normally in correctpol sition, permits` -itto more back, as occasion may require.

'lhe combination of a work-supporting surface, an edge-folding mechanism, and a told-compressingand ironing or smoothing mechanism, relativclycon- .structed and arranged substantially as described.
